Pack Stack GoLogo Design Contest

First, thank you to all so far for you efforts :) After seeing the orange and yellows lets punch it up a bit, add some more color of your choice all but green. Also lets stay away from grey in the logo (our fault we were not clear on that), the background color of all the items such as truck, trailer, bins is a medium grey so the logo will get lost if it is grey. Looking forward to more, thank you!
Logo must also display well in a single colour, (white) against a solid background.

Hello All

Please refrain from using grey. The truck where the logo will be used is also a med dark grey. We need the logo to have some punch. If you have used grey in the above please redo without GREY...
